In terms of broad inclusion, the closure: operating device of the present invention, comprises a shaft oranalogous member rotatably mounted in asuitable support and operably'coupled tothe 5 associated closure so that theclosure may be opened and closed by rotary motion of the shaft. The only portion of the device which is accessible to unauthorized persons is a lever or handle which is mounted for free rotationuponan end 20 operable by properly authorized persons is provided for 'rigidly con necting the lever to the shaft so that the shaft Thi5 conmay be left in such position that the lever and shaft are positively interconnected but which may be manipulated soas to instantly disconnect the leverfromthesha ft, so thatit is.freely rotatable thereupon, the effect being positively to 30 lock the closure in either fully openedor fully closed position, as the case might be, inasmuch, as the handle itself is the" only portion of the device which is accessible; to unauthorized pert .7 sons and consequentlytherotary motion :of the 3s The invention possesses other.objectsandvalushaft which is necessary; for movement of the doorcannot beeffected. Means arealsoipmvided for so retaining the shaftin either ofits two-extremes of movementthat in order tomove theclosure or door the shaft itself'must firstbe 4c i turned, thereby preventing inadvertent movement of the door from .fully openedaor fully closed position. i v l l \Morespecifically describedgfour improved closure operating and locking device'is illustrated 45 upon Figure 1 as beingloperably associated with a doorfi of thetype forming the subject matter of our aforementioned application Serial No.

620,884, which is mountedbymeansof a suitable bracket structure] for pivotallmovement to and from closed position, about an axis 8 ,spacedla material distance inwards from;,the inner face of the door fi. Figure 1 illustrates the door in its closed position, and itis adapted to be opened by swinging in a clockwise direction as viewed l upon that figure until it is disposed substantially horizontally and in an overhead position, leaving the doorway unobstructed for passage therethrough.

Our improved locking and operating device is indicated in its entirety at H and comprises a shaft |Z rotatably mounted in and extending through the wall l3 which defines the opening i l with which the door 6 is associated. Preferably the shaft I2 is enclosed within a suitable housing, such as a piece of tubing it, the outer end of which is threaded into a collar ll aflixed to the outer face of the wall l3. Extra rigidity is imparted to the housing lS-by means oi": a brace IS on one end of which a collar is is formed and on the other end of which a flange 2| is provided. The collar l5 encircles the housing it, which is rigidly secured thereto as by a set screw 22; and the flange 2| is rigidly secured to the inner face of the wall i3 as by a lag screw i To the inner end of the shaft 52 a crank 26 is securely fastened as by a set screw 21. To the outer end of thecrank 26 one end of a link 23 is pivoted and the other end 29 of the link 28 is pivoted to'the bracket 1, the parts be ing so proportioned and arranged that when the crank 26 swings upwards from the position illustrated upon Figure l to the position illustrated upon Figure 2, the door (5 will be swung'frorn closed position tofully opened position. Where as movement of the crank 23 through substantially 180 is all that is necessary to swing the door 5 through its entire range of movement, the crank 25 is capable of moving slightly beyond both of its dead center positions, whereupon a lug 3 rigid with the crank 25, will come into enengagement with abutments 32 or 33 as the case might be, carried by a collar 34, rigid with the inner end of the tubular housing is. This serves to retain the door 6 in either itsfully opened or its fully closed position until the shaft l2 and the crank 26 carried thereby are moved, thereby preventing inadvertent movement of the door by forces applied to the door itself. In other words, it is necessary for the operating device to receive the necessary actuation before the door can be moved.

The operating means whereby the rotary motion of the shaft l2 necessary to move the door 6 may conveniently be effected by properly authorized persons through the expedient of a handle or lever 4| carried by the shaft l2. This lever 4| is mounted upon that end if of the shaft l2 which projects through the wall I3; and inasmuch as the protruding end 42 of the shaft I2 is completely enclosed within the head 53 which is formed at one end of the lever li, the only portion of the operating device I i which is accessible on the outside of the wall 113, is the lever 4| itself. Therefore, by so mounting the lever 4! upon the shaft l2 that the leverv is freely rotatable upon the shaft but adapted to be rigidly connected thereto by means operable by authorized persons only, we have provided an effective lock for the door 6, which makes it impossible for any but authorized persons to open the door.

A flange 45 is shown as being rigidly secured to the shaft I2 asby a pin 43 extending through the flange 45 and the end of the shaft 2, although it should be understood that any other suitable means for securing the flange 46 in position upon the shaft I2 may be employed. In order to permit assembly of the device, the head 43 is composed of two portions 49 and 5|, secured together as by a plurality of cap screws 52. In the portion 49 a recess 53 is formed for the reception of the flange 46 and the adjacent portion of the shaft l2; and the shaft l2 extends through a suitable opening 54 in the portion 5| of the head 43 into the recess 53, the above described parts being so proportioned and arranged that the lever 4| is freely rotatable with respect to the shaft The means for releasably locking the lever 4| to the shaft l2 includes a notch 56 formed in the periphery of the flange 45 and a pin 5'! slidably mounted in the head 43 for movement axially of the pin 51 and parallel to the axis of the shaft l2 in such position that it may optionally be seated within the notch'55 or withdrawn therefrom. For this purpose, a portion 58 of reduced diameter is formed on the pin which may be brought into registry with the flange 45 as illustrated upon Figure 4, under which circumstances the lever 4| will be freely rotatable'upon the shaft E2. The pin 5'! is slidably disposed within aligned holes 53 and 6| in the portions 49 and 5| respectively of the head 43, and is continually urged as by a spring '52 so as to move the reduced portion 58 out of registry with the flange 41 and to bring a portion 33 of greater diameter into registry there with so that it seats withinthe notch 55. The pin 51' is of such length that when the larger portion 63 is disposed within the notch the forward end 64 of the pin protrudes beyond the forward face of the head 43, therebyproviding a conveniently manually operable portion which may be pressed into the head 43 against the action of the spring 52.

Within another recess 66 in the head-43 a detent (ii is pivotally mounted as by a pivot pin 68 rigid with the portion 5| of the head 43 and extending loosely through a laterally projecting arm 63 of the detent 61. The lower portion H of the detent Si is enlarged to provide sufficient stock to accommodate an aperture 1'2, into which protion comprises a barrel TI, rigidly anchored in the head 43 as by a set-screw 18, and the cylinder M, which may be rotated within the barrel ll only by means of the appropriate key. The parts are so proportioned and arranged that when the cylinder I4 is turned from the position in which it is illustrated upon Figures 3 and 4, the pin 13 will be carried downwards, swinging the detent iii in a counter-clockwise direction as viewed upon Figure 3, so as to withdraw the upper end 8| of the detent 51 from the hole 53 within which the pin 51 is slidable. This motion of the detent 6'! is resisted by a leaf spring 82 under compression between the lower edge of the detent 61 and the bottom of the recess 66; but of course the detent 61 cannot be swung upwards to move the end 8| into the hole 59 except when the reduced portion 58 of the pin 57 is in registry with the flange 46, as will be understood clearly from Figure 4. However, owing to the fact that the aperture l2 affords ample clearance for the pin 13, the cylinder 14 of the lock 16 may be returned to the position illustrated upon Figures 3 and 4, to permit removal of the key, without pressing the pin 5! back into the head 43, under which circumstances the upper end 8| of the detent 61, will be pressed against the larger portion 63 of the pin 51. Consequently, when the pin 51 is pressed back into the head 43, the detent 6'! will be forced upward by the spring 82 so that it will retain the pin 51 in the position illustrated upon Figure 4 by engagement with the shoulder or abutment 66, which separates the portions 58 and 63 of the.

from the above description of its component parts.

When the pin 51 is depressed so. that it occupies the position in which it is illustrated upon Figure 4, the lever 4| will be free to rotate upon the shaft l2, so that unauthorized persons will be unable to effect movement of the door 6. How- I ever, by insertion of the proper key into the lock 16, the cylinder 14 may be turned, whereupon the lock pin 13 willwithdraw the detent 61 from engagemehtwith the abutment 86, permitting the spring 62 to force the pin 51 outwards, provided the lever 4| is in such position with respect to the shaft l2 that the notch 56 is disposed in registry with the pin 51. Preferably, the parts are so arranged that the notch 56 is in the underside of the flange 46 when the door 6 is closed, and the pin'51 isdisposed directly under the axis about which the lever 4| is adapted to swing, when the lever hangs straight downwards, thereby causing the pin 51 automatically to. come intoregistry. with the notch 56 when the door. 6 is closed and the handle 4| is permited to hang freely. This afi'ords convenience inthe use of the deviceinasmuch as it permits the operator to unlock the door by the simple expedient of inserting the key and turning the cylinder 14 of the look without having to devote any attention to the position occupied by the lever 4|, which is swung by gravity into that position which brings the pin 51 into registry with the notch 56, thereby enabling the larger portion 63 of the pin 51 to move into the notch 56 and lock the lever 4| to the shaft |2 when the detent 61 is withdrawn. Looking of the door may be effected simply by pressing the portion 64 of the pin 51 into the head 43, thereby removing the portion 63 fromthe notch 56, which will permit the lever 4| to turn freely without effecting rotation of the shaft I2. When this 0ccurs,'thedetent 61 will be pressed upwards by the spring 82, thereby retaining the pin 51 with-v drawn from engagement with the flange .46 until the lock 16 again is actuated. v
